Abstract
1,073,601. Formers. R. E. CHAPMAN. Dec. 3, 1963 [Sept. 4, 1962], No. 33789/62. Heading B5A. A process for applying a relief pattern to a former for use in dip-moulding comprises impinging an abrasive material on the parts of the former where it is desired to apply the impressions. The former may be made from porcelain, glass or metal, and the abrasive may be sand, alumina or metal shot. In particular the former may be made from glazed porcelain, the parts of the former which are not to be impinged are shielded by a mask of rubber or metal, and the impressions are applied by sand blasting at a pressure of 1¢ lb. per square inch to produce an unglazed portion. The relief pattern may comprise indicia. The former may be a shoe former or a glove former in which a shallow groove may be formed around the wrist portion thereof. The formers are used for moulding articles of vinyl polymers or copolymers which contain a major proportion of combined vinyl chloride.
